The characteristics and advantages of the invention are set forth in the description which follows, which is made in reference to the attached drawings by way of indicative example only, in which:

FIG. 1 is a perspective view of the machine which is the subject of the present invention with the upper table being partly cut away.

FIG. 2 is a perspective view on a smaller scale of the machine shown in its squaring-up, rough-planing, position.

FIG. 5 is a view similar to FIG. 2, but showing the machine in shaping position. I

FIG. 6 is a partial view in vertical section, taken through the shaft supporting the squaring-up and planing tool.

FIG. 7 is a sectional view taken along the broken line VII-VII in FIG. 6.

FIG. 8 is a partial view in perspective showing a device which remedies the overhang of the shaft supporting the squaring-up or planing tool, and adjusting the height of the latter.

FIG. 9 is a partial view showing the device for applying the tension to the drive belts of the tool-holding shafts.

In reference to the drawings, and according to one method of embodiment, the machine is constituted by a frame 1, with a U-shaped section, whereof the middle part 2-constitu'tes the table of the planer.

Frame 1 has a transverse slot 3 in which there can move a shaft 4, supporting the squaring-up or planing tool 5, whereof one of the bearings 6 is integral with the upper part of a column 7 which can slide axially in a sleeve 8 integral with one of the lateral faces of said frame.

On frame 1 there is fixed a table 9, forming a supporting surface during the sawing, shaping and squaring-up operations, and, with a view to carrying out the latter operation, a pivotal table 10 is added to table 9.

Shaft 4, by means of a belt, pulleys, chain and sprockets drives the usual pair of rollers designed to insure the entrainment of the materials during the planing.

Bearing 6 has an extension 11 supporting an electric motor 12 fixed on a platen 13 which has a journal 14 that can pivot in a bearing 15 in said extension 11 with the axis of said journal being perpendicular to the shaft 16 of the motor and to the shaft 4.

Platen 13 forms the bearing of a shaft 17 designed to receive a circular saw or a shaping wheel with said shaft being parallel to that of the motor 12. By rotation of the platen, it is possible to tilt shaft 17 as desired and as a matter of fact, the amplitude of rotation is limited to 90, one of the two extreme positions corresponding to vertical shaping, while the other positions correspond to various inclinations of the saw or shaper.

Extension 11 which is a corner piece, has a circumferential opening 18 which, by means of a screw and nut 19 connected to motor 12, with manual operation lever, makes it possible to immobilize motor 12 at the desired inclination.

Manipulation of the moveable frame. supporting shafts 4 and 17 including column7, bearing 6, extension 11 and platen 13, is insured by a shaft 20 immobilized in translation in a radial extension 21 of sleeve 8 and controlled by a crank 22. Shaft 20 has at one end, an endless screw 23 engaging with a tangential pinion 24 meshed with the teeth of a rack 25 on column 7.

Sleeve 8 has a longitudinal slot 26 which permits, for example by means of a manually operated screw 27, to clamp said sleeve on column 7 to insure immobilization of the latter.

With shaft 4 overhanging, its free end will pivot in a bearing 28 connected to bearing 6 by crossbraces, not shown, and including a fork 29 engaged on a vertical guide 30 with the immobilization of the said fork on said guide being insured by a screw 31. In so doing, the two ends of shaft 4 are held perfectly during the planing and squaring-up.

Guide 30 is graduated to permit adjustment of the height of shaft 4.

The entrainment of shafts 4 and 17 from motor 12 is insured by two belts 32 or 33, belt 32 entraining shaft 4, and belt 33 entraining shaft 17 with the pulley 34 of the motor shaft being designed to receive one belt at a time. This very simple device makes it possible to obtain, at low cost, a high degree of security in the running and utilization of the machine inasmuch as it is not possible to entrain the two tool-holding shafts at the same time.

FIG. 9 shows the simple way of tensioning belts 32 and 33. To do so, the face 35 of the motor supportis articulated at 36, toward its perimeter, on platen 13, and has a circumferential opening 37 which permits, with the aid of a manually operated screw 38, and a prisoner nut, or vice-versa (not shown), to immobilize said face on the platen 13.

From the position represented in FIG. 2, it is merely necessary to manipulate crank 22 to lower the mobile assembly, in order to bring the planing tool at a suitable distance from the lower table 2. When this tool is in bottom position, it is possible either to change the saw blade mounted on shaft 17, or to pivot platen 13 in order to position the said shaft vertically for a shaping operation with the adjustment of the saw or the positioning of the shaping iron being carried out by manipulating crank 22.

Finally, it should be noted that the free end of shaft 4 can comprise a mandrel 39 or the like, receiving a mortising tool, horizontal supports 40, FIG. 8, making it possible to fix a removable table, FIG. 1, in the usual way, and making it possible to mortise on the fly or to attach an ordinary mortiser, with operation of the transverse and lateral displacements by two levers. The end of the shaft can be provided with any other woodworking device such as a disc sander, a flexible, a wood lathe, and the like.
